Aeroacoustic Consortium Formed to Foster World Class Research

Aircraft noise will continue to be a concern well into the current millennium. Challenges associated with the issue will be tackled beginning in October, when internationally renowned experts start residing at NASA Glenn Research Center to perform cutting-edge engine system aeroacoustics research in a ground-breaking collaboration.

This collaboration-the first ever of its kind at Glenn-is called the AeroAcoustics Research Consortium (AARC). Its purpose is to address difficult, technical barrier issues and develop innovative ideas, methods and concepts. The consortium will be an extremely visible, cost effective, strategic national asset for NASA, industry, other governmental agencies and universities.

"We need to refocus the efforts of active researchers in the field on the new challenges and to bring in new researchers as well," said Glenn Chief Scientist Dr. Marvin E. Goldstein. "We hope that these researchers will work collaboratively with researchers from both NASA Glenn and industry to meet the future aircraft noise reduction goals."

The AARC has three main objectives:

  • To attract international acoustics experts to interact with Glenn and industry researchers.
  • To concentrate research efforts on engine noise prediction and reduction.
  • To emphasize fundamental understanding of noise generation from engine components through analytical and experimental methods.

Four researchers are scheduled to participate in the consortium thus far: Dr. Krishan Ahuja, Georgia Technology, Atlanta, GA; Dr. Hafiz Atassi, University of Notre Dame, Notre Dame, IN; Dr. Don Hanson, formerly of Pratt & Whitney, Chester, CT, but participating as an independent; and Dr. Sanjivi Lele, Stanford University, Stanford, CA. All research participants are selected on the basis of proposal applications. Applications are accepted and reviewed periodically by the management team on an ongoing basis.

Initial emphasis will be on high-risk technology in the following areas: jet noise source definition and prediction; Computational AeroAcoustics; and fan broadband noise.

The AARC will organize and host technical meetings, seminars, workshops, short courses and conferences that will bring additional focus and visibility to aeroacoustics research. The first of these will be a Jet Noise Workshop at OAI (Ohio Aerospace Institute) in Cleveland, OH from November 7-9.

The collaboration is facilitated by OAI. Partners include Glenn, NASA Langley Research Center, Hampton, VA; Boeing Commercial Airplane Group, Seattle, WA; General Electric Aircraft Engines, Cincinnati, OH; and Honeywell Engines, Phoenix, AZ.
